Neumann, Abilene, Tex. Application March 15, 1932, Serial No. 599,053 11 Claims. (o1. 137-139 'Thisinvention relates to an electro-magnetic fgas regulating and igniting attachment designed primarily for use in connection with gas stoves, but it is to be understood that an attachment, in

' accordance with this invention may be employed for any purpose for which it is found applicable, and the invention has for its object to provide, in a manner as hereinafter-set forth, an attachment for igniting a gas burner and regulating a gas supply by remote control.

To the above ends essentially and to others I which may hereinafter appear, the invention consists of such parts andcombination of such parts as fall within the scope of the invention as claimed.

In the drawings: I Figure l is a vertical sectional viewof. an electromagnetic gasregulating and igniting attachment in accordance with this invention with the controlling and regulating valve thereof shifted from its normally closed position to open position, and further illustratingby way of example, the. arrangement of the igniting element v with respect to ages burner, the latter being 3* shown in dotted lines.

Figure 2 is a section on line 2-.-2 Figure 1. Figure 3 is a section on line 33 Figure L 1 Figure 4 is a section on line 4'-4' Figure 1.

Figure 5 illustrates in elevation a detail of the 1 39 control element.

Figure 6 is a sectional detail of. the'regulating element.

The attachment includes a gas regulating clement 1, an igniting element 2 and a control ele- 3' ment 3. The elements 1 and 2 are incircuit with the element 3.

The circuit conductors of a service line are indicated at 4, 5 and which lead from an electrical source, not shown. As shown by way of example,

. the conductors l, 5 are attached to a plug 6 for 0 at 9,- 10, the former leads from a source of gas supply, notshown andthe latter to theburner ll; Casing 8 has secured to its outer periphery on opposite sides thereof, couplingmembers 12, 13' for the line sections 9,-10 respectively. The

i member 12is arranged above member 13. Witly in casing 8 is arranged a diametrically extending gas intake pipe '14 which leads from line'section 9. Positioned within the upper portion of casing *8, is'a regulating valve mechanism 15, comprising a housing 16 openingat its top and bottom and provided between its transverse median and its upper end with a partition 17, to form that part of the housing above the partition as a gas intake chamber 18 into which "opens the pipe 14 at a point in proximity to partition 1'7, the latter being formed axially thereof with an opening 19 providing a valve stem guide. The housing 16 at a point between its transverse median and lower end is formed with a partition 20 provided with an axially arranged opening 21 having its- Wall beveled to form a valve seat 22. That part of the housing below partition 20 provides a gas discharge chamber 23. The intermediate portion of the housing is of greater diameter than its upper and lower portions and in connection with the partitions 1'7 and 20 provides a valve chamber 24. The chamber 18 is closed by a removable plug 25. Casing 8 has an opening 26 in its top so that access can be had to plug 25. Arranged within chamber 24 for engaging valve seat 22 to shut off communication between chambers 23 and 24 is a controlling valve 27 formed integral with the lower end of a stem 28, which extends upwardly through opening '19. The valve 27is normally in closed position to shut oi? the gas supply to the. burner and is illustrated as being shifted to open position. When in its normal position it engages the valve seat 22. The valve 27 is also formed is arranged a receptacle of non-magnetic material formed of a head part and a pair of depending spacedtubular extensions 36, 37 which extendthrough and frictionally engage with the solenoids 31', 32respectivelyand have operating "therein the cores33, lid-respectively. The exten- "sions open into the head part 35 and the latter has an opening 38 in its top and a verticalcollar 39'registering with the wall of opening 38. The

collar 39 extends into the bottom of and is secured to housinglfi. The lower ends of the tubular ext nsions are plugged asst rsulatedx and snugly fitted l on the 1 tubular :extensions. ,1The: solenoids-are aadjustedzupon' the extensions a ismallvdistance zzabove the;.point-- where 5 they .have x the greatest pulling, power and: such adjustment can-.be had with: littlepressure. :The cores "are :at their highest points when-adjustmentnof the :respectivewsolenoidwcoils are made. =Thisza'djustm'ent makes it (possible to. raise-or -lowerthe valver27.;=gtadually.
